SPECIFICATION forming part of Letters Patent No. 760,049, dated May 17,1904.

Application filed June 17,1902. Serial Nil. 112,048. (No model.)

.To all whom it may concern:

Be it known that we, WILLIAM N. WINFIELD and JAMES BARKER, citizens ofthe United States, residing at Detroit, in the county of 5 Wayne andState of Michigan, have invented certain new and useful Improvements inBinders, of which the following is a specification, reference being hadtherein to the accompanying drawings.

1 The invention relates generally to temporary binders of the classwherein sectional posts connect the binder-covers, thepost-sectionsbeing detachable one from another so that the length of the post orposts may be I varied for the purpose of increasing or diminishing thesize of the binder to accommodate the number of leaves or papers to befiled.

The invention has particular reference to a sectional post for bindersof the type referred 2 to; and it consists, essentially, in a novel typeof lock for the post-sections, as will be more fully hereinafterdescribed and illustrated.

In the drawings, Figure 1 is a perspective View of a portion of theledger or binder covers and the sectional connecting-posts therefor.Fig. 2 is a section through the covers and one of the connecting-posts,and Fig. 3 is a section taken on line a; w of Fig. 2.

In the drawings thus briefly described the 3 reference-letters A and Bdesignate the upper and lower covers of the binder, carrying hingedthereto and as a part thereof, respectively, the clamping members CandD.

E designates the sectional posts connecting the covers and carried. byone of the latter, the complementary cover having openings F formedtherein, through which the posts extend, whereby it may be moved uponthe posts as guides to or away from the lower cover.

4 The lower section of each post is provided with a tubular extension a,threaded upon its interior and adapted to be inserted within an opening6, formed in the clamping member D. These sections are rigidly connectedto the cover by means of threaded bolts 0, extending through theclamping member, as shown, and engaging the threaded tubular extension.

The remaining sections of each post are formed each with a socket 7) inone end and a reduced portion or pintle c at the opposite 5 end. Thesockets b are adapted to engage over pintles' (0 upon the lowersections, and the pintles c engage within the sockets of the nextadjoining post-section. The means for locking these sections to form arigid post are arranged upon the exterior of the post and comprise,preferably, though not necessarily,

an individual exterior look for each adjoining pair of sections. Inconstruction the lock consists, preferably, of a spring-latch H, fixedlysecured to one section at .its lower end and adapted to engage within arecess formed within the next adjoining section. A groove (Z of greaterdepth than the thickness of the latch is formed longitudinally in each 5post-section. Within this groove the latch is arranged and on account ofthe depth of the groove lies Wholly within the external diameter of thepost. In forming the recess in the adjoining section a shoulder c isproduced, 7 over which the head 0' of the latch engages. This shoulderis reduced, so as to allow the upper portion of the latch to lie whollywithin the external surface of the adjoining post-section in the mannerindicated in Fig. 1.

It will be obvious from the construction of the lock that in additiontoholding the sections against independent longitudinal movement it alsoserves to prevent independent rotary movement. Furthermore, the latch orSo look is automatic in itsoperation, which enables the'size of thebinder to be varied in a minimuiinspace of time.

The top section of each post is provided, preferably, with a cap D,having a socket 5 formed centrally therein in which the sectionpintleextends. The cap is also provided with a shoulder it, which is engagedby the latch upon said top section.

The upper cover A is provided with lock- 9 ing means whereby it may besecured to the binder-posts in different positions of adjustment. Thelocking means referred to consist, preferably, of blocks J, arrangedwithin recesses K in the clamping member, one opposite each post, and aset-screw L, extending through the edge of the clamping member andbearing against the block, as shown, the blocks being adapted to bejammed against the posts, and thereby lock the cover in the desiredposition.

The binder, as shown in Fig. 1, is constructed with posts composed oftwo sections. If it is desired to increase the size of the binder, thecaps may be removed by prying outwardly the spring-latches, so as todisengage the latter from the shoulders h, and additional sections addedto the posts in the manner shown in Fig. 2. The caps are then replacedupon the top sections, and the binder is in readiness for use.

What we claim as our invention is- 1. In a binder, thecombination withthe covers, of a sectional connecting-post, the sections of the posthaving recesses in the outer surface thereof, andmeans fitting therecesses for locking the sections against independent endwise movement,the parts when assembled forming a smooth, unbroken surface.

2. In a binder, the combination with the covers, of a sectionalconnecting-post, the sections of the post having recesses in the outersurface thereof, and means fitting the recesses for locking the sectionsagainst independent endwise and rotary movement, the parts whenassembled forming a smooth, unbroken surface.

3. In a binder, the combination with the covers, of a sectional posttherefor, the sections of the post having recesses upon the outersurface thereof, and automatically-operating means fitting the recessesfor locking the sections against independent endwise movement, the partswhen assembled forming a smooth, unbroken surface.

4. In a binder, the combination with the covers, of a connecting-posttherefor, comprising a plurality of detachable sections having recessesin the outer surface thereof, and an exterior lock fitting the recessesfor connecting each pair of adjoining sections, the parts when assembledforming a smooth, unbroken surface.

5. In a binder, the combination with the covers, of one or moreconnecting-posts therefor, each composed of a plurality of sections oflike diameter, having a recess in their outer surface, and anautomatically-operating lock fitting the recesses for connecting eachpair of adjoining sections, the parts when assembled forming a smooth,unbroken surface.

6. In a binder, the combination with the covers, of one or moreconnecting-posts therefor, each composed of a plurality of superimposedsections of like diameter having a sliding engagement one with another,and each of said sections having a recess in its outer surface, and aspring-lock carried by each section engaging the adjoining section, saidlocks being fitted in the recesses in the outer surface of the sections,and the parts when assembled forming a smooth, unbroken surface.

'7. In a binder the combination with the covers, of one or moreconnecting-posts there for, each composed of a plurality of detachablesections having a recess in their outer surface and a lock connectingthe adjoining sections and. holding the latter against inclependentrotary and longitudinal movement, said lock being fitted in the recessesin the outer surface of the sections, and the parts when assembledforming a smooth unbroken surface.

8. In a binder, the combination with the covers, of one or moreconnecting-posts therefor, each composed of a plurality of detachablesections, having recesses in their outer surface, and anautomatically-operating lock connecting each pair of adjoining sections,and holding the latter against independent rotary and longitudinalmovement, said locks being fitted in the recesses in the outer surfaceof the sections, and the parts when assembled forming a smooth unbrokensurface.

9. In a binder, the combination with the covers, of a connecting-posttherefor, comprising a plurality of detachable sections, having a recessin their outer surface, and a lock fitting within the recesses in theouter surface of the sections for connecting each pair of adjoiningsections, the parts when assembled forming a smooth unbroken surface.

10. In a binder, the combination of a lower section having anupwardly-extending post said post comprising va plurality of sectionshaving recesses in their outer surface, and a lock fitting in therecesses, the parts when assembled forming a smooth unbroken surface, acomplementary upper section slidably mounted upon the post, a slidingblock fitting in a recess in the upper section adjoining the post, andmeans on the upper section for forcing the block into engagement withthe post to lock said upper section in its adjusted position.
